Bio — John O’Donnell | 2026 GB4 Championship Driver

John O’Donnell enters the 2026 GB4 Championship just one year after beginning his racing career in 2025, without a traditional karting background.


His 2025 U.S. debut season produced four podium finishes across five race weekends, including a Regional F3 victory at Thunderhill Raceway Park and second-place finishes in the Skip Barber Formula Series at Virginia International Raceway and New Jersey Motorsports Park.


Born in Korea and raised in Boston, O’Donnell now transitions to the UK with Pace Performance, bringing rapid progression and a disciplined, engineering-focused foundation to one of Europe’s most competitive junior single-seater championships.
